I spend my time on one problem: how a machine can make a consequential decision and then prove it was reasonable.

That problem found me in enterprise security, where I have worked for twenty years — first at Citi, then at Merck — building and running the systems that decide what an organization does about risk. Security is a useful place to learn it, because the decisions are constant, the evidence is incomplete, the stakes are real, and somebody eventually asks you to justify every call you made.

Along the way I became an inventor on pending patent applications covering belief-memory architecture for AI reasoning systems. I write software. Not diagrams of software — the actual thing, in production, myself.

Before any of that I served twenty years in the U.S. Army and retired as a Command Sergeant Major in the 82nd Airborne Division, one of the youngest in the Army at the time. It is the least relevant line on my résumé technically and the most relevant line on it otherwise.

I also spent years as a working military artist, which is a strange thing to find on this page and I have decided to leave it there.
